Resolution: Not A Bug
> Zombie hunting tips!
> --------------------
>
> Key: HBASE-12410
> URL: https://issues.apache.org/jira/browse/HBASE-12410
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Michael Stack
> Priority: Major
>
> Here are some tips from Mr Charlton Heston (@dima spivak) and World War Z
> Brad Pitt ([~apurtell]), famous Zombie killers, on how to figure why tests
> are hanging:
> bq. Set -Dsurefire.timeout=0 to the mvn command which sets the process
> timeout to unlimited.
> Above is good for figuring what is sticking around.
> bq. When hunting zombies locally you can also set the first part and second
> part fork modes to "always" so each test runs in its own VM, then loop the
> unit test suite, watch for stragglers, then jstack. Works well because you
> can be sure every stack in the dump is relevant for the hung test.
> Lets keep this issue open and add tips for tests for nailing those that won't
> die.
